We would love to get feedback on
what we have so far, as well as hear about what you'd like to do with our API.

Please remember: This is a BETA version of the API.

You're welcome to take a look and try things out. The Swagger documentation would be a
good place to start.

While the endpoints are pretty stable, the parameters and responses may change at any time while we are developing
it. Please keep an eye on the PharmGKB Blog or the PharmGKB
Twitter feed for an announcement of the final, stable API.
The final release will also be noted in the documentation.

Data Usage & License

If you are planning on using the API for more than trivial tasks,
please let us know. This helps us anticipate the amount of traffic to
expect. Even more importantly, it helps us justify the need to support this API to funding agencies.

Limitation: please limit requests to 2 per second. Too freequent requests will result in a 429 response.
